Law

Kutztown University of Pennsylvania - Understanding Intellectual Property - There's a lot of controversy in the news and on the internet today about what exactly "intellectual property" is, what it means to hold a copyright, what exactly a copyright is, and how you register one and what it means to have intellectual property rights over a non-tangible object. The course also discusses international IP issues and copyright protection issues, and the impact of piracy on policymaking and legal issues.

MIT - Law and Society - Prof. Susan S. Silbey - We all know that the law is a set of rules that lay out proper behavior and order in our society, but where do they come from? Where did the concept of "the law" originate, and how does it differ from place to place? This course seeks to explain the history of the law, the applicability of the law and how laws are formed, written, and enforced, and offer the student a basic understanding of the legal system and its social implications.

The Open University - Privacy Rights and the Law - Specifically geared at UK citizens and European citizens, this course form the Open University examines UK privacy laws and the rules laid out by the European Commission on Human Rights. How the different bodies interpret privacy rights is also examined, along with a basic examination of how the rest of the world sees the right to privacy—or whether their citizens have a right to privacy at all.

MIT - The Supreme Court, Civil Liberties, and Civil Rights - Prof. Malick Ghachem - Everyone talks about civil liberties and their personal rights, but few people take the time to investigate them, read up on what rights they do and don't have, and where their personal rights stop and the rights of others begin. This course will help you understand your civil rights and liberties as issued by the constitution and other legal bodies and documents, as well as the powers that those legal bodies (including the Supreme Court) have to put a finer point on those rights and interpret them.
